"Company Contributions"? (those don't show up anywhere on yoru W-2)
Or your contributions to a company 401k? Those are different issues.
_______________________________________
1) I tried it for a 74 y.old person. who contributed 10,000 to a 401k (As noted on his W-2).
No errors indicated, nor is an over contribution indicated anywhere using desktop software ...BUT Make sure you only enter your W-2 as-is, don't double-enter your 401k as a contribution in the IRA/ROTH IRA contribution section...a 401k is NOT an IRA.

2) OR...are you talking about a Solo 410k for self-employed people ?
..... how each is handled can be entirely different and is important for you to say-so when you ask a question about such things.

3) Of course, it is possible to do so (Excess contributions to a 401k) but usually only with multiple employers at any age.

4) OR are you actually referring to an IRA contribution...and incorrectly calling it a 401k contribution.....then NO, you cannot contribute to an IRA after a certain age...you can do a rollover to one, you just can't make any more "contributions"
